Ethereum’s Fusaka Upgrade and BPO Fork: A Strategic Leap in Scalability and Layer-2 Efficiency

The ethereum network has successfully activated its first Blob Parameter Only (BPO) fork, a direct and strategic scaling outcome of the Fusaka upgrade executed on December 4, 2025. This technical milestone, which went live smoothly at 4:49 PM ET, represents a significant evolution in Ethereum's roadmap by decoupling parameter adjustments from full network upgrades. The core achievement of this BPO fork is a substantial 67% increase in blob capacity, raising the limit to 10–15 blobs per block. This enhancement is not merely a numerical boost; it is a targeted infrastructure upgrade designed to directly benefit the ecosystem's scaling backbone—Layer-2 rollups. By expanding the dedicated data space (blobs) available per block, the network effectively lowers the cost and increases the throughput for rollups to post transaction data to the mainnet. This move is a clear bullish signal for Ethereum's long-term value proposition, as it tangibly addresses scalability—a historically critical bottleneck. Improved Layer-2 efficiency translates to a better user experience (lower fees, faster transactions) on countless dApps, potentially driving higher adoption and network activity. While the activation saw a temporary participation dip among 25% of validators, the overall smooth transition underscores the robustness of Ethereum's governance and upgrade mechanisms. As of December 2025, this upgrade solidifies Ethereum's methodical approach to scaling through its rollup-centric roadmap, directly strengthening its competitive position in the smart contract platform arena. The increased data availability paves the way for the next generation of high-throughput decentralized applications, making the Ethereum base layer more capable and cost-effective for the entire ecosystem it supports.

Ethereum’s Fusaka Upgrade Activates BPO Fork, Expands Blob Capacity

Ethereum’s first Blob Parameter Only (BPO) fork is now live, marking a strategic scaling MOVE following last week’s Fusaka upgrade. The update boosts blob limits to 10–15 per block—a 67% increase—without requiring a full hard fork. Layer-2 rollups gain immediate benefits from the expanded data capacity.

The Fusaka transition executed smoothly at 4:49 PM ET on December 4, despite temporary participation drops among 25% of Prysm client validators. Network improvements include enhanced validator efficiency and groundwork for future upgrades like Glamsterdam.

Etherscan confirmed the new parameters via social media, noting the change reflects Ethereum’s incremental approach to scaling. Blob throughput now grows without disruptive chain modifications, preserving stability while accommodating rising demand.

SEC's Atkins Suggests Most ICOs Fall Outside Securities Regulation

Former SEC Chair Paul Atkins declared Tuesday that the majority of initial coin offerings should not be classified as securities. His remarks signal a potential pivot in regulatory stance—one that could unshackle a fundraising mechanism long stifled by federal oversight.

The comments arrive as crypto markets show renewed vigor, with Ethereum-based tokens and decentralized finance protocols leading gains. Market participants interpret the statement as a tacit endorsement of alternative capital formation methods.

Ethereum Climbs to 3-Week High Amid Mixed Market Signals

Ethereum surged toward $3,400, buoyed by weak U.S. employment data fueling expectations of monetary policy easing. The rally defies concerns over dwindling network activity and tepid Leveraged interest.

Network fees plummeted 62% in 30 days, starkly underperforming rivals like Base (+108%) and Polygon (+81%). Layer 2 expansion outpaces Ethereum's mainnet, with Fusaka upgrade-driven efficiency gains failing to offset collapsing DEX volumes ($23.6B → $13.4B) and DApp revenues hitting 5-month lows at $12.3M.

Vitalik Buterin Condemns Elon Musk's X Platform for Amplifying Hate

Ethereum co-founder Vitalik Buterin has publicly criticized Elon Musk's stewardship of X, accusing the platform of enabling coordinated hate speech. The rebuke follows X's €140 million EU fine for failing to curb misinformation—a regulatory failure Buterin suggests reflects deeper algorithmic rot.

Meanwhile, Farcaster—a decentralized social network championed by Buterin—is pivoting toward financial utility. Its new wallet-first model prioritizes on-chain trading over community interactions, signaling a strategic shift in decentralized social media's evolution.
